FORM FOR CONCRETE CONSTRUCTION Filed April 16, 1948 Patented May 2, 1950 UNITED STATES PATENT OFFICE 2,506,485 FORM FOR CONCRETE CONSTRUCTION Angelo A. Boudousquie, Sr., New Orleans, La.

Application April 16, 1948, Serial No. 21,329

1 Claim. (01. 25-131) This invention relates to a building form for use in erecting walls of concrete or the like.

By way of background, it may be noted that "in the art, the most conventional type of form used for pouring concrete is still that requiring the erection of special form, using boards and wooden framing, designed for the erection of a particular wall. After this single-use form has been erected, and after the concrete which has been poured therein has fully set, the form is broken away, and another form must be erected anew for the next Wall to be poured. Forms adapted for assembly and disassembly for reuse have previously been devised, but have not found assembly with maximum speed, that can be reused, and which moreover can be made very inexpensively.

It is a further important object to provide a form construction as described wherein the speedy assembly and disassembly mentioned is means between the panels which in effect automatically brings about proper placement of each panel relative to each other panel in erection of the form.

Still another important object of the inven tion is to provide a form as stated wherein the panels used are so designed as to be capable of easy manufacture on a modular plan, that is the panels readily lend themselves to construction in multiples of a designated number of inches.

Another important object is to provide a form for concrete construction which when erected will be unusually strong, despite the fact that there is not required, in the assembly thereof, the

use of fastening means such as bolts, nails, or the like.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is a, face View of a portion of a partially erected form embodying panels constructed in accordance with the invention, the form being viewed from the outside.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a perspective view of one of the panels.

Referring to the drawing in detail, each panel comprises a pair of permanently connected panel sections. These comprise an outside panel section generally designated 5, and an inside panel section generally designated 6. The panel sections are of any suitable strong material, such as plywood or cement asbestos board, to provide examples of material that can be used, Other materials having the requisite strength for resisting the pressure of the poured concrete after assembly of the form can well be used. It is worthy of note at this point, additionally, that the' panels may be of any desired size. Preferably, panels formed in accordance with the invention are on a modular plan, and can, for instance, be in multiples of 16", both as to length and width.

The panel sections 5 and 6 are each placed fiat against the other, in an offset arrangement to be described in greater detail hereinafter, and are permanently secured by any suitable means.

readily permitted through cooperating aligning M They can, for example, be permanently bonded together or otherwise adhesively secured to bring forth the completed panel.

Referring to the outer panel section 5, this is rectangular and flat conformation. In each of the four corners of the section, a quarter-round transverse recess 1 is provided. Spaced apart half-round transverse recesses 8 are formed in the top and bottom edges of the section, the number of the recesses 8 varying according to the length of the panel.

Formed in the respective end edges of the panel section 5 are half-round recesses 9, and as in the case of the recesses 8, the number of these can varyaccording to the width of the panel section.

vFormed centrally of the section are spaced openings Ill, the number of which also can be varied according to requirements, two being shown in the present instance.

The inside panel section 6 is of the same dimensions, as to length and width, as the outside panel section 5. However, when the section 6 is positioned against section 5 for the purpose of being secured thereto, it is offset relative to the section 5 so that one end portion H projects beyond the adjacent end edge of the section 5, and one side portion [2 projects beyond the adjacent side edge of the outside panel section. In the present instance, the projecting side portion I2 is at the bottom of the completed panel.

Obviously, so positioning the section 6 results II and the projecting portion l2 of the insidev panel section, the panel section is cut away as at l5 to provide a recess thewalls ofWhi'ch are at right angles to each other, the intersection or: said walls being rounded off to correspond and register with the adjacent quartr-round i'e'ces's 1. This construction is best shown in Figure 1.

The formation of the inside panel section 6 is arrangement. By reason of this construction,

the threading of wires through any openings isv strength; capable of assembly and disassembly completed by providing therein middle openings 55 51 of. th p n Y9 P IQ QQ? a 1 fm fifi iforthepouring of-concrete can be achieved in various ways.
